UNITED STATES JOHN STUART KNEE, OF GRAND RAPIDS, MICHIGAN.

HUMIDIFIER.

Application filed October 4, 1923. Serial No. 666,518.

To all who 1a it may concern:

Be it known that 1, JOHN STUART KNEE,

a citizen of the United States, residing at Grand Rapids, in the countyof Kent and State of Michigan, have invented new and useful Improvementsin Humidifiers, of

which the following is a specification.

The present invention relates to humidifiers; and its object is toprovide a humidifier having improved means for circulating the watertherein, and being adapted for use in connection with heat radiators ofcommon form.

This and any other objects hereinafter appearing are attained by, andthe invention finds preferable embodiment in, the structure hereinafterparticularly described in the body of this specification and illustratedby the accompanying drawings, in which:

Figure l is an end View of a heat radiator, and a transverse sectionalView of a humidifier carried thereby taken on line 11 of Figure 4;

Figure 2 is a top plan view of a portion of 2 the humidifier, and asectional view of a portion of the radiator taken on line 22 of Figure1;

Figure 3 is a similar view, but showing the humidifier supported at oneside of the radiator;

Figure 4 is a vertical sectional view of a portion of the humidifiertaken on line 4 at of Figure 5;

Figure 5 is a horizontal sectional view of the same taken on line 55 ofFigure 4E; and

Figure 6 is an edgewise end view of a plate in the humidifier.

In the embodiment of the invention illus trated by the drawings, myhumidifier 1 is shown employed in connection with, and supported upon, aheat radiator 2 of common form, comprising a plurality ofparallelly-disposed hollow members 3, having opposite portions 4, 5,spaced apart by alined voids 6. My humidifier 1 is in form a deep andnarrow vessel, as shown, with an open top 7 sides 8, ends 9 and bottom10. It may be removably inserted into the radiator in termediate theopposite portions 4:, 5 of the radiators members 3, its bottom restingon the lower connecting portions 11 of said portions, as seen in Figures1 and 2; or the humidifier may be positioned in contact with one side ofthe radiator as seen in Figure 3, in which position it may be supportedby the rod 12 extending toward the opposite side of the radiator andconnected as by the rods nut 13 to the bar 14 engaging said oppositeside. The humidifier vessel 1 is provided with a filling mouth 15, andhas a removable plate 16 positioned vertically edgewise in the vesseland spaced from its opposite sides 8 by the spacing members 17 carriedby the plate. This plate is, in the construction illustrated, spaced at18 from the vessels bottom, and is spaced from its opposite ends 9, andhas at its end edges adjacent the ends of the vessel, semi-circularrecesses or openings 19.

It will be understood that the water in the vessel 1, being heated bythe radiator, will circulate in the humidifier and that this circulationis caused particularly by the vessels being heated more at its sidewhich is adjacent the radiator in the form seen in Figure 3, then it isheated at its opposite side; and even when the vessel is inserted in theposition seen in Figures 1 and 2, the side of the vessel which is neareran outside wall of the room where located, will not be heated as much asits opposite side. It will be seen also that by reason of this unevenheating of the opposite sides 8, 8 of the vessel, the plate 16positioned between said sides and spaced from both divides the narrowbut deep chamber of the vessel 1 and thus keeps the unevenly heatedwater adjacent said sides from quickly intermingling near the vesselsbottom; but causes a more complete circulation of the water and a moreuniform heating thereof throughout, by forcing the heated water to risethrough the recesses 19 of the plate and thus pass at the plates endsfrom one side of the plate to the other.

The invention being intended to be pointed out in the claims, is not tobe limited to or by details of construction of the particular embodimentthereof illustrated by the drawings or hereinbefore shown or described.

I claim:

1. In a structure of the character described: a heat radiator; anopen-top deep and narrow vessel supported thereon; a plate positionedvertically edgewise in the vessel and spaced from its opposite sides andfrom its bottom and from at least one of its ends.

2. In a structure of the character described: a heat radiator; anopen-top deep and narrow vessel supported thereon; a

plate positioned vertically edgewisein the vessel and spaced from itsopposite sides and having a plurality of recesses inits endedgesadjacent the ends ozfi. the vessel.

3. In a structure of the character described: a heat radiator; anopen-top deep and narrow vessel supported thereon; a removable platepositioned vertically edgewise inthe vessel and spaced: from its0ppesite ends and carrying spacing members adapted to space the platefrom the opposite sides oi the vessel.

In testimony whereof I, have hereunto set my; hand at Grand Rapids,Michigan, this 26th day of September, 1923.

JOHN STUART KNEE.
